Research And Application Of Cloud Desktop Virtualization Architecture

Currently the virtualization technology is growing fast. There are some virtualization products excellent, VMware ESX Server, IBM PowerPC, Citrix Xen, Microsoft Hyper-V and KVM, etc. In this paper, there is designed a cloud desktop virtualization architecture based on the open-source virtualization technology KVM, the overall architecture is divided into three parts, KVM virtualization server, Web management middleware and SPICE client. Then the paper focuses on the QEMU-KVM virtualization technology, open-source desktop virtualization protocol SPICE, KVM Web management middleware and open-source virtualization tool library Libvirt and other key technologies and implementation details.In this paper, we also designed virtualization platform based on KVM, designed and developed the Web KVM management tools based on Libvirt. In this paper, an improved Hungarian algorithm is presented to solve the virtual machine resource allocation problems. Finally, the virtualization platform is deployed. The virtualization platform designed all use the open-source technology and it has high theoretical value and practical value.
